SKATE.

SPECIFICATION forming part of Letters Patent No. 244,929, dated July 26, 1881. Application filed May 9, 1881. (No model.)

To all whom it may concern:

Be it known, that we, WILLIAM GEORGE RAWBONE and JOSEPH LOX'ION RAwBoNE, both of the city of Toronto, in the county of York,in the Province of Ontario, Canada, have invented certain new and useful Improvements onSkates, of which the following is'a specification.

The object of the invention is to arrange the clamps for securing the skate to the boot in such a manner that they can be readily adjusted to suit the various sizes of boots; and it consists, essentially, of pivoted front clamps operated by angular slots in a plate adjusted by a rod passing below the supporting-plates of the skate and connected to the heel-clamp, which is attached to or formspart of a sleeve fitting into a recess below the heel-plate, the said adjusting-rod being arranged to adjust the front and heel-clamps simultaneously, as hereinafter more particularly explained.

liigure 1 is a perspective bottom view of our skate. Fig. 2 is a plan with the front and heel-plates shown in dotted lines.

In the drawings, Ais the blade of the skate, and B the front plate connected to the blade, as shown.

0 is a heel-plate supported on an inverted arched bracket riveted to the blade of the skate, as represented.

E is a sleeve fitting into the arched recess in the bracket D, and to which the heel-clamp F is secured.

G is the adjusting-rod, located as shown, and secured to the heel-clamp F so that it can revolve but cannot move lengthwise. A butterfly-nut, H, or thumb-screw, is secured to the rod G behind the clamp F. The other end of the rod G is screwed and passes through a nut in the plate I. This plate has angular slots a cut in it, as shown, to receive the pins 1). These pins are attached to the front clamps, J, which are pivoted, as shown, upon the bottom side of the front plates, B. It will be noticed that the heel clamp F is turned up to form a shoulder, against which the front edge of the heel of the boot butts. Owing to the manner in which the-adjusting-rod G is connected to the pivoted front clamps and heelclamp, as described, the clamps can be readily adjusted to suit the diiferent sizes of boots. The major portion of the adjustment being effected by moving the rod longitudinally with the skate, which action, owing to the angular slots in the plate I, adjusts the front clamps, 5 while the heel-clamp is permitted to move, owing to its connection to the sleeve E, as (le scribed. When thus moved the required distance the clamps can be pressed against the boot by turning the rod G, its screw, actingin 6o a nut on the plate- I, drawing the front and rear clamps against the boot, or vice versa, as required.

We are aware that sliding-sole clamps of skates have been drawn together by a sliding 6 plate provided with diverging slots to engage with the clamps; that similar clamps have been drawn together by diverging slots in soleplates against which they are drawn by a screw; and we are also aware that a bar piv- 7o oted at its center to a skate-plate, and provided with an upwardly-projecting jaw at each end, has been turned on its pivot to cause its jaws to clamp a shoe-sole bya sliding rod carrying a pivot to engage with the said pivoted bar; 'and therefore we do not broadly claim either of the above-mentioned devices.

In our invention the sole-clamping jaws'are formed on the outer ends of two bent bars, which are pivoted at their other ends, one to each side of the skateplate, and are provided with downwardly-projecting pins which engage with diverging slots in a sliding plate under the pivoted bent angle-bars. By this construction the angle-bars are secured to the skate by a single rivet in each, and are held securely in place by the sliding plate having the diverging slots.

What we claim as our invention is- 1. In a skate, and in combination with the go sole-plate B thereof, the bent right-angle clamp-bars J J, each secured by a single pivot to the sole-plate, one at each side thereof, and provided with projecting pins b b, the sliding plate I, having diverging slots to receive said 9 5 pins 12 b, and to operate the pivoted clamp bars, and the screw G, for imparting moveby the same screw which operates the toe- 1o ment to the sliding plate I, substantially as clamps, substantially as and for the purpose and for the purpose specified. specified.

2. In combination with the sole-plate D a 5 rightangle clamp bars J J, pivoted one 01; each side of plate D, pins 1) I), sliding plate I,
